445nm Blue Line Laser Alignment Review In process of highly clear and accurate line alignment at different work distances, it is not simply relying on manual line drawing or printing work, but making even better job with Berlinlasers 445nm blue line laser alignment. After its easy use of 5V, 9V 1000mA DC power supply, employing an import 445nm blue laser diode within 50mW to 100mW, it projects highly visible blue laser beam, but also makes highly clear blue reference line projection within the maximum work distance of 25 meters. This blue line laser module applies qualified glass coated lens and separate crystal lens within 10 to 110 degree. It projects high linear quality and straight blue line within 0.5 meter to 6 meters. Within long lasting line aligning work of 8 to 10 hours, after correct use of output power and optic lens degree, it assures the lowest price, and the highest stability blue reference line projection for multiple application fields, including laser show, laser displaying, textile garment processing and high tech work etc. https://www.berlinlasers.com/blue-line-laser-alignment
